Hi Niels,
as you probably know, some selection of G-70
data take place by using pointers. For instance: choose a User Program using Set List. Therefor I think, G-70 OS can have problems searching original data because of not intended re-organization your SSD. Perhaps it is possible to you creating a new data base on external memory. Testing what happens working with this data, you will have a feeling what is going wrong. Of cource, that's only I'm thinking about your problem. Specialists will be back soon, hopefully.
